The lawsuit follows a successive string of protests, demonstrations and violence across France that began with student demonstrations for better conditions. Temporary curfews were enforced in some areas, and repeat demonstrations are planned for this upcoming weekend. Trade unions have called for a general strike on 5 November.
Goudon said the union's action targets the state's alleged responsibility for the security failures witnessed over the past week. The union represents thousands of national police officers and has long warned about under-resourcing and unclear command structures during major protests. The claim will be heard by the administrative court, which handles liability disputes involving the state.
France has experienced periodic protest movements and police-tension controversies in recent years. The current wave escalated after student marches, with clashes reported in several cities. The government has not yet responded publicly to the union's legal action.
